The lowermost limitation that this project technology regulation demonstrates limits to measure pump and its drive motive, auxiliary equipment to industrial device maneuver asks. Machine of design of the performance that this project technology provides pair of metric pump, structure, material, drive, experiment, mark, pack and purchase waited for a regulation. 2.

Standard, standard and regulation 2.

1 outside setting except this project technology, the standard that still should observe the demonstrate on pump data table (latest edition) , be like: Condition of technology of GB9236 metric pump; GB7783 metric pump tries proved recipe way; API675 metric pump (PositiveDisplacementPumps-ControlledVolume) . 2.

2 when this project technology regulation and when appointing standard happening to contradict, with this project technology the regulation is accurate. At the same time the bargainor answers to clarify contradictory place to buyer with written form, in order to remind buyer the attention is solved. 3.

General principles 3.

1 unless otherwise specified, machine of pump, drive reachs his to assist equipment to should be below appointed lowest and highest environment temperature apply to outdoors start and operate continuously. Successive operational cycle should not under 8000 hours. 3.

The 2 prototype without test cannot be accepted, only the course produces the pump of test and verify actually to just can be accepted. Alleged production test and verify is to show pump operates the experience that there is safety of two years of aboves to run at least below the condition in likeness. 3.

3 divide outside having a regulation additionally, the bargainor should be offerred include pump, shaft coupling, drive machine and all whole pump that assist device inside aircrew, assure quality of whole pump aircrew. 3.

4 divide outside having a regulation additionally, machine of pump, drive, shaft coupling and shield, auxiliary equipment should be installed go up in same base. 4.

Function 4.

1 metric pump should be being operated or section discharge all can be moved when blame operation condition, its adjust than be at least 10: 1(namely 100 ％ of 10 ％ ～ are rated discharge limits) , and in 25% ～ the stability precision of metric pump inside 100% limits should be in 1 ％ of ± less than, degree of linearity and reproduction sex precision should be in 3 ％ of ± less than. 4.

2 attune measure a watch or adjust handwheel scale precision should prep above ± 0.

The demonstrative precision of 1% . 4.

What the rated discharge of 3 metric pump should be equal to an user to put forward at least is the biggest (operate) the 110 ％ of discharge. 4.

Rated power of 4 electric machinery should be equal to metric pump at least power of the largest shaft (the power loss that contains gear case, shaft coupling) K times. K value presses the watch is taken calm. 55115%Pa>55110%4 of ≤ of 19125%19<Pa of ≤ of 3150%Pa of ≤ of Pa(kW)KPa of power of the largest shaft.

NPSHa of surplus of 5 effective cavitation and NPSHr of indispensible cavitation surplus should use same datum plane. The difference of NPSHa and NPSHr is less than be equal to 0.

When 6m, should undertake cavitation surplus experiments. 5.

The structure is designed 5.

1 bear control a part 5.

1.

1 pump allows the greatest outlet pressure to should be equal to pump forehead to decide the 110 ％ of outlet pressure at least. 5.

1.

2 all bear control a part (include inlet pressure to affect area) should send by pump design of the greatest outlet pressure allows below temperature, what what take stuff is allowable stress value: To homebred pump, should not be more than HG20531-93(container of cast-iron, cast steel) of the regulation the biggest allowable stress value; To importing pump, what should not be more than ASMESectionVIII to set is the biggest allowable stress value. 5.

2 interface 5.

2.

1 unless data is expressed,go up to have a regulation additionally, all interface all are flange. 5.

2.

2 unless otherwise specified, homebred pump imports and exports joins flange should accord with the regulation of GB9112, entrance pump imports and exports joins flange should accord with ANSIB16.

1 reach 16.

The regulation of 5. The flange that diameter or ply are more than above standard also allows. 5.

5 bearing bearing should be standard form, the bearing is not mark that must not use manufactory proper motion to make. 5.

If 6 bumper are appointed on data table, bumper of imports and exports should be offerred by the bargainor, its type should talk things over jointly by buyer and bargainor. 5.

7 relief valve 5.

7.

Relief valve of oil pocket of 1 membrane pump should automatic restoration and adjust, maintenance, change convenient, its set calm pressure to should be metric pump forehead to decide the 110 ％ of pressure at least. 5.

7.

2 if be appointed on data table, the exterior relief valve that force plunger pump uses should be offerred by the bargainor. 5.

8 auxiliary pipeline 5.

8.

1 if need,lubricant, refrigeration is mixed sealed rinse wait for pipeline system, the bargainor should be offerred and installation is mixed in pump (or) on base. 5.

8.

The pipe of system of 2 all pipeline, connect should not be less than 1/2 inch (13mm) , its wall is large should not be less than 1.

6mm(1/16 inch) . 5.

8.

3 unless otherwise specified, 1-1/4(32mm) , 3-1/2(90mm) , 7(175mm) , 9(225mm) inch pipe fitting cannot be used. 6.

Material 6.

After 1 material is decided by buyer, fill in to go up in pump data table. If the bargainor thinks other data is more appropriate, can offer written report, but whether to use those who need to get buyer to affirm. 6.

2 unless otherwise specified, of carbolic steel, low-alloy steel corrode abundant to spend take 3mm, tall alloy steel takes 0mm. 6.

3 forbidden use contain asbestine fibrous material. 6.

4 when carrying organic dissolvent, material of forbidden use balata. 6.

5 carry combustible explode easily or of poisonous medium bear press a spare parts to cannot use cast-iron data. 6.

6 outside dividing austenite stainless steel, when medium or environmental temperature ≤ - when 20 ℃ , the bargainor should be belonged to to basic gold and solder contact makes V concussion experiment. 7.

The workshop experiments 7.

The project that 1 workshop experiments sees pump data is expressed. 7.

2 hydraulic proof pressure should are highest 1 what allow actuating pressure.

5 times, but not under 0.

14MPaG. Stability precision experiment is surely option, its precision should be in 1 ％ of ± less than, experiment of reproduction sex precision and experiment of degree of linearity are optional, its precision should be in 3 ％ of ± less than. 7.

Regulation of 3 pairs of buyer needs to show up the examination that witness or test project, the bargainor should shift to an earlier date 20 days to notify the buying party at least after affirmatory trial date, so that buyer can be seasonable,attend. 7.

The result that 4 blame witness an experiment should be recorded and deliver buyer is approbated. 8.
